Pteridophytes are classified into four classes namely, Psilopsida; Pteropsida; Sphenopsida; and Lycopsida. Sporopsida doesn’t belong to this set of classification. Therefore, it is the odd among the four.

Odd One Out
There are four divisions of the extinct vascular plants: Lycopsida, Pteropsida, Sphenopsida, and Sporopsida. Among these, the odd one out is Sporopsida.
Explanation
- Lycopsida: These are the club mosses, which have microphyll leaves and are characterized by their small size and creeping or upright growth habit.
- Pteropsida: This division includes the ferns, which have megaphyll leaves and are typically larger in size compared to club mosses.
- Sphenopsida: This division consists of the horsetails, which have jointed stems and scale-like leaves arranged in whorls.
Odd One Out - Sporopsida
- Sporopsida is not a commonly recognized division of vascular plants. It is not a valid taxonomic group and is not commonly used in plant classification.
- The term "Sporopsida" may be a mistake or a misinterpretation, as it does not correspond to any well-defined group of plants in the traditional classification system.
Therefore, among the given options, Sporopsida stands out as the odd one out due to its lack of clear taxonomic classification and recognition in the field of plant biology.
